Thanks for the additional info, I didn't know the data was processed by county. I chose the "Northeast Topo United States Part 1 of 3" because it covered the area of interest and was an editors choice. But roads aren't included for Addison and Caledonia counties in Vermont.
I don't have any prior experience with topo maps but "Northeast Topo United States Part 1 of 3" is very nice in that it shows rivers with some width rather than just a blue line plus it has more extensive POIs than the others I looked at. What I attempted was to select mostly from this map and then substitute Caledonia county from the Savage topo. This seemed to work, at least it generated appropriate files on a thumb drive. I haven't figured out how to look at the result with the PC so when the GPSr arrives I'll copy these files to the microsd card and see whether it works.
Thanks for helping this newbie get started.
